There are many problems
in the world. Scientists investigate problems through different types
of experiments and observations, but engineers design different types
of solutions. Engineers try to solve problems for society. They design
structures that allow politicians, builders, and other planners to make
decisions for society. Engineers are the link between science and
mathematics. Design is an important component to the scientific
method.

Engineers consider many
factors that would allow a product to be used. They analyze using
mathematical skills to see if the design is good. For example, in building a
bridge, an engineer would have to consider many things including the types of
materials and how to build them to be safe and sturdy. They would create
exact designs that allow builders to create a structure. Engineers usually
test their designs with computer simulations and real models.
